What is Dynamic Testing?

Dynamic testing is a critical aspect of software testing where the actual behavior of a program is tested by providing different inputs. It ensures that the software functions correctly under various conditions and user interactions. Here's a brief overview of dynamic testing:

Key Aspects of Dynamic Testing in Software Testing:

  • It involves executing the software to observe its behavior.

  • Tests are conducted with real-world inputs to find errors and issues.

  • The goal is to validate the software's performance and functionality.

Example of Dynamic Testing in Software Engineering: 

For instance, when testing a Login Page, if the system allows the username "cromacampus" but produces an error for "cromacampus@123," dynamic testing uncovers these variations in response. It ensures that the software behaves as intended under different input scenarios.

In essence, dynamic testing simulates real user interactions to validate the software's behavior, ensuring it functions correctly and reliably in diverse usage situations.

Need for Dynamic Testing

  • Validate software during and after installation.

  • Verifies efficient software behavior.

  • Requires runtime execution for testing.

  • Provides insights into dynamic code behavior.

  • Evaluate real-time software performance.

  • Assesses resilience under environmental stresses.

Characteristics of Dynamic Testing:

To grasp the fundamentals of software testing techniques, it's essential to understand the key attributes of dynamic testing:

  1. Validation Stage: Dynamic testing is typically implemented during the validation stage of software testing.

  2. Program Execution: It involves actively running the software program to assess its behavior and functionality.

  3. Functional and Non-Functional: Both functional and non-functional pects of the software are evaluated through dynamic testing.

  4. Bug Identification: Dynamic testing is effective in identifying bugs and issues within specific software.

  5. Reliability Validation: It serves as a tool for validating the reliability of the software application.

  6. Code Implementation: Unlike static testing, dynamic testing requires the implementation of the software's code to obtain expected outputs.

  7. Direct Software Testing: Dynamic testing is conducted directly on the software application, distinguishing it from other testing methods.

  8. Formal Approach: It offers a more formal and structured approach to testing activities, including test execution, coverage assessment, reporting, and test case identification.

Significance of Dynamic Testing

  • Detecting Varied Behaviors: Dynamic testing is essential because it helps identify how software behaves under different conditions and inputs. This process ensures that the software responds appropriately to diverse user interactions.

  • Unveiling Inconsistencies: It helps uncover inconsistencies within the software, such as discrepancies in data presentation. For instance, in an E-commerce application, a product price displayed as "$100.00" on one screen and "100 USD" on another can confuse users. Dynamic testing ensures consistency in such scenarios.

  • Identifying Hidden Issues: By actively using the software as an end user would, dynamic testing can reveal issues that may not be apparent through static testing methods. These issues may include runtime errors, performance bottlenecks, or unexpected crashes.

  • Enhancing User Satisfaction: Consistent and reliable software enhances user satisfaction. Dynamic testing helps deliver a software product that functions as intended, creating a positive user experience.

  • Maintaining Quality: Dynamic testing is integral to ensuring software quality. It verifies that software meets the specified requirements and performs well under real-world conditions.

Types of Dynamic Testing in Software Engineering

Dynamic testing is divided into two main categories, each serving a unique purpose:

  1. White Box Testing: In white box testing, the automation tester knows the internal workings of the software, including its code and design. The primary goal here is to examine how the system performs based on its underlying code. This type of testing is typically carried out by developers or experts familiar with programming.

  2. Black Box Testing: Black box testing is the opposite. Testers are not privy to the internal code or design. The main aim of black box testing is to verify the functionality of the system under test without any knowledge of the system's internal structure. Testers execute the complete test suite, and no programming knowledge is required.

Black Box Testing Further Breaks Down into Two Types:

  • Functional Testing: This ensures that all the features of the software work according to the specifications. Testers provide input, check the output, and compare actual results with expected results. Various levels of functional testing include:

    • Unit Testing: Testing small, individual parts of the code, often done by developers.

    • Integration Testing: Combining testable individual units after unit testing, performed by developers or testers.

    • System Testing: Ensuring the system meets requirements, typically done by testers when the system is ready.

    • Acceptance Testing: Performed by end-users to verify business requirements are met, indicating readiness for deployment.

  • Non-Functional Testing: This type focuses on non-functional attributes of the system, such as memory, performance, and robustness. Various non-functional testing techniques include:

  • Performance Testing: Checking system response times under network load.

  • Recovery Testing: Verifying the system's ability to recover from crashes and hardware failures.

  • Compatibility Testing: Testing how the system behaves across different environments.

  • Security Testing: Ensuring the application's robustness and access control.

  • Usability Testing: Assessing user comfort and satisfaction with the system.

In essence, these dynamic testing categories help ensure software functions as expected, whether you're digging into the code's nitty-gritty (white box) or testing it without knowing its internals (black box).

Dynamic Testing Techniques

In the Software Testing Life Cycle (STLC), dynamic testing techniques involve a series of tasks that are interlinked, relying on the completion of each preceding task. Here's a breakdown of the dynamic testing process, starting from test case design:


1. Test Strategy: Before delving into the process, it's essential to establish a test strategy. This strategy considers available resources, timeframes, testing objectives, scope, testing phases, the testing environment, and any potential challenges or risks. Once the strategy is defined and approved by management, the actual test case design begins.

2. Test Design and Implementation: In this phase, we identify the following elements:

  • Features to be tested

  • Derive the test conditions

  • Derive the coverage items

  • Derive the test cases

3. Test Environment Setup: Ensuring that the testing environment closely resembles the production environment is crucial. This phase involves installing the build and managing the test machines to create a consistent environment for testing.

4. Test Execution: During this phase, test cases are executed. The software is actively tested based on the test cases created earlier.

5. Bug Reporting: If the actual results during testing do not match the expected results, the test case is marked as "Fail," and a bug report is logged to document the issue.

In summary, dynamic testing techniques involve a sequence of steps, with each step building on the one before it. These steps ensure comprehensive testing of the software's features, identify issues and facilitate efficient bug reporting and resolution.
